The game was initially scheduled for Friday night but canceled while the city was lockdown. The lockdown was lifted on Friday evening, about three hours before Tsarnaev was apprehended alive in nearby Watertown, Mass. He'd been hiding in a boat behind a home. Police arrested him after a tense standoff that featured gunfire and reports that he'd been killed, as his brother Tamerlan was the night before.

While the 12:30 p.m. Saturday start was tentatively set before Tsarnaev's capture, officials left open the possibility that it would be canceled again.

That won't be necessary.

The move from Friday to Saturday means that the Penguins' previously scheduled game against the Buffalo Sabres has been moved to Wednesday.

The Bruins had already been forced to reschedule two games, including on Monday night just hours after the bombings, which complicated logistics—but none of that matters anymore.

Friday night, as Saturday is sure to be, was cathartic for citizens, law enforcement and first responders alike; officers applauded when the news broke, as did bystanders in Watertown while police vehicles filed out.
